Drone technology uncovers three hidden Aboriginal rock shelters in Blue Mountains

Researchers have successfully identified three unregistered Aboriginal rock shelters in the rugged Blue Mountains region of Australia using drone-based LiDAR technology, marking a significant advancement in archaeological survey methods. The shelters, which contain distinctive red hand stencils and stone artifacts, represent important cultural sites that were previously unknown to official records.

The discovery was made in collaboration with the Dharug Custodian Aboriginal Corporation, whose involvement ensured accurate cultural documentation and respectful treatment of the sacred sites. This partnership proved essential in properly identifying and cataloging the archaeological significance of the rock formations and their contents.

The application of drone LiDAR technology offers researchers a non-invasive method to survey difficult-to-access terrain, addressing a longstanding challenge in archaeological work across Australia's varied landscapes. The technology's ability to penetrate dense vegetation and map complex topography has proven particularly effective in mountainous regions where traditional survey methods face significant limitations.

Researchers indicated that ongoing studies will assess how this innovative approach can be adapted for use across different Australian landscapes. If successful, the methodology could substantially improve the detection and preservation of previously undocumented indigenous cultural heritage sites across the continent, offering new opportunities to document Australia's rich Aboriginal history.
